Definitions

  • the present invention relates to a process for the alkoxy carbonylation of carboxylic acid functionalized alkenes or esters thereof.
  • WO01/10551 discloses a carbonylation reaction using a Pd catalyst system.
  • a problem associated with such carbonylation reactions is that the catalyst system tends to inactivate over time. Especially in processes wherein the catalyst is used repetitively or continuously, inactivation of the Pd catalyst system may form a problem.
  • the problem is understood to reside in the reduction of the ionic Pd to metallic Pd. Such process is also referred to as the formation of Pd black. To compensate for the loss in activity additional Pd catalyst must be added. Pd black may adhere to the wall of the reactor.
  • WO0110551 proposes to carry out the carbonylation process in the presence of polymeric dispersants.
  • a disadvantage of the use of polymeric stabilizers is that they are not required for the chemical conversion per se and their use means extra cost.
  • Another disadvantage of using a polymeric dispersant is that it must be separated from the carbonylation product.
  • the invention discloses herewith a process for the carbonylation of optionally functionalized alkenes, said process comprising:
  • the process of the invention may be a continuous process. Any continuous reactor type is suitable. Examples of suitable reactor types are continuous stirred-tank reactor (CSTR) and plugflow. In a CSTR reactor once steady state is reached the concentration of components in the reactor does not change anymore: reactants are withdrawn and substrate is added such that their concentrations remain the same in the reactor. In a plugflow reactor, for example a packed bed reactor (PBR) the conversion depends on the residence time, which in turn is a function of its position in the reactor. Plugflow reactors are often selected when the product is susceptible to a further reaction. If the alkene carbonylation product is reactive, a PFR reactor is preferred. If the alkene carbonylation product is not very reactive, for example in the case of dimethyl adipate, a CSTR reactor, or a series of CSTR reactors, is preferred.
  • CSTR continuous stirred-tank reactor
  • plugflow reactor for example a packed bed reactor (PBR) the conversion depends on the residence time, which in turn is a function of its position in
  • the steady-state amount of the carbonylation product in the continuous process may depend on the type of reactor and is preferably selected such that the catalyst system is stabilized and the yield is satisfactory.
  • no alkene carbonylation product has yet been formed. This situation may for instance occur when a continuous process is started for the first time, or for example after a process is re-started, e.g. after a maintenance stop.
  • the catalyst system cannot be stabilized by the alkene carbonylation product because there is no alkene carbonylation product yet. Therefore, it is essential that the alkene carbonylation product is initially present in the continuous process.
  • the process of the invention may be a repetitive batch process, wherein said repetitive batch process preferably further comprises
  • the repetitive batch process according to the invention preferably comprises two or more consecutive processes.
  • the repetitive batch process according to the invention comprises three or more consecutive processes, more preferably four or more consecutive processes, five or more consecutive processes, six or more consecutive processes, seven or more consecutive processes, eight or more consecutive processes.
  • a repetitive batch process including steps (b) and (c) has the advantage that in the recovery step (b) no very stringent separation is required.
  • the inventors have realized that the stabilizing effect of the alkene carbonylation product on the catalyst system of the invention may be applied in a repetitive batch process by recovering the catalyst system in the presence of said alkene carbonylation product.
  • a catalyst stabilizer is used the skilled person when recovering said catalyst will try to retain as much stabilizer as possible.
  • the efficiency of the recovery of the catalyst system from the reaction product is never 100% and some catalyst stabilizer will be lost. This may for example be the case when reaction involves the production of volatile compounds and where these compounds are removed by distillation. In such cases a catalyst stabiliser may also be removed by evaporation.
  • the recovery in step (b) of the process of the invention does not have to be very efficient; in fact, the presence of alkene carbonylation product with the catalyst system is advantageous.
  • the recovery step (b) may be easier and/or less expensive.
  • the recovery may also advantageously be done using simple and inexpensive separation technology and/or with less-trained operators.
  • Another advantage is that by using the recovered catalyst system obtained in step (b) in the carbonylation reaction in step (a), no extra addition of alkene carbonylation product is required, which may be less cost and time consuming. It would not be obvious to recover the catalyst system in the presence of alkene carbonylation product.
  • the ratio of the alkene carbonylation product:Pd is at least 500:1 based on dry weight.
  • the ratio of the alkene carbonylation product:Pd in the process is at least 900:1; more preferably at least 1750:1, all based on dry weight.
  • step (b) does not necessarily mean that the catalyst system is completely separated from the alkene carbonylation product. Complete recovery would mean that catalyst system would be devoid of the alkene carbonylation product, and this may result in inactivation of the catalyst system. Although it is an aim of step (b) to recover the catalyst system from the alkene carbonylation product, it is essential that the catalyst system always comprises at least some alkene carbonylation product.
  • the ratio of the carbonylation product:Pd in the recovering of the catalyst system in step (b) is at least 500:1 based on dry weight.
  • At least 10% (w/w) of the catalyst system in step (a) may be the recovered catalyst system obtained in step (b). More preferably at least 20% w/w, at least 30% (w/w), more preferably at least 40% (w/w), 50% (w/w), even more preferably at least 60% (w/w), at least 70% (w/w), even more preferably at least 80% (w/w), 90% (w/w) of the catalyst system in step (a) may be the recovered catalyst system obtained in step (b). Most preferably all catalyst system in step (a) is the recovered catalyst system obtained in step (b).

  • the optionally substituted alkylene group which R 5 or R 6 represents, or which R 5 and R 6 represent is a lower alkylene group.
  • a lower alkylene group is defined as an alkylene group having 4 C atoms or less, more preferably having 3 C atoms or less, even more preferably having 2 C atoms or less, most preferably the lower alkylgroup is methylene.
  • the number of C atoms in R 5 and R 6 are not necessarily the same.
  • R 5 may have 2 C atoms whereas R 6 may have one C atom, or vice versa.
  • the alkylene group which R 5 and/or R 6 represent are non-substituted.
  • R 1 , R 2 , R 3 , and R 4 in the bidentate diphosphine of formula I or formula II may be tert-butyl, R 3 and R 4 may be methylene, and/or R or X may be ortho-phenylene or orthonapthalene. R 5 and/or R 6 are preferably methylene.
  • a suitable ligand is ⁇ , ⁇ '-bis(di-tertbutylphosphino)xylene.
  • the length of the bridge formed by R spanning P 1 and P 2 in the bidentate diphosphine of formula I or of X spanning R 5 and R 6 in the bidentate diphosphine of formula II may be between 1 and 20 atoms, more preferably between 2-10 atoms, even more preferably between 2 and 6 atoms.
  • WO01/68583 describes a process for the carbonylation of ethylenically unsaturated compounds using a catalyst system comprising Pd and a bidentate biphosphine ligand.
  • WO01/685 suggests that the carbonylation reaction can be done in the presence of the ester carbonylation product (e.g. an alkene carbonylation product) as a solvent.
  • the aim of WO/0168583 is to increase the selectivity with respect to linear carbonylation products.
  • the ester carbonylation product is one of a long list of suitable aprotic solvents that can be used in order to increase the selectivity with respect to linear carbonylation product.
  • WO/0168583 is silent with respect to continuous or repetitive batch processes, and all examples of WO/0168583 refer to single batch reactions. Moreover, WO/0168583 is silent with respect to a possible stabilization effect of the Pd catalyst system by the presence of ester carbonylation product.
  • the hydroxylgroup comprising compound may be an alkanol, preferably methanol.
  • Suitable solvents include ketones, such as for example methylbutylketone; ethers, such as for example anisole (methyl phenyl ether), 2,5,8-trioxanonane (diglyme), diethylether, tetrahydrofuran, 2-methyltetrahydrofuran, diphenylether, diisopropylether and the dimethylether of diethyleneglycol; esters, such as for example ethyl acetate, methyl acetate, dimethyl adipate and butyrolactone; amides, such as for example dimethylacetamide and N-methylpyrrolidone; and sulfoxides and sulphones, such as for example dimethylsulphoxide, di-isopropylsulphone, sulfolane (tetrahydrothiophene-2,2-dioxide) 2-methylsulfolane

  • the acid can also be an ion exchange resin containing sulphonic acid groups.
  • An especially preferred source of anions derived from an acid having a pKa below 3.0 is methylsulphonic acid, tert -butyl sulphonic acid and/or 2,4,6-trimethylbenzenesulphonic acid.
  • Suitable sources of Pd in the process of the invention include its salts, such as for example the salts of palladium and halide acids, nitric acid, sulphuric acid or sulphonic acids; palladium complexes, e.g. with carbon monoxide, dienes, such as dibenyzlideneacetone (dba) or acetylacetonate, palladium nanoparticles or palladium combined with a solid carrier material such as carbon, silica or an ion exchanger.

  • a salt of palladium and a carboxylic acid is used, suitably a carboxylic acid with up to 12 carbon atoms, such as salts of acetic acid, proprionic acid, butanoic acid or 2-ethyl-hexanoic acid, or salts of substituted carboxylic acids such as trichloroacetic acid and trifluoroacetic acid.
  • a very suitable source is palladium (II) acetate.
  • the source of Pd may be selected from the group consisting of palladium halide, palladium carboxylate or Pd2(dba)3.

  • the product of the methoxycarbonylation of ethene, methyl proprionate, can be further reacted with formaldehyde to form methyl methacrylate.
  • the present invention can lower the cost of an already existing process for the production of methyl methacrylate.
  • the carbonylation process of the invention is an alkoxycarbonylation, preferably methoxycarbonylation.
  • the alkene in the process of the invention is optionally functionalized.
  • the functionalization may include hydroxyl, amine or amide, and carboxylic acid or esters thereof.
  • Preferred functionalized alkenes are carboxylic acid functionalized alkenes.

  • the alkene carbonylation product preferably has 4-20 C atoms, more preferably 5-8 C atoms, even more preferably 6 C atoms.
  • Suitable carboxylic acid functionalized alkenes are pentenoates or esters thereof, preferably pentenoate methyl esters. Alkoxycarbonylation of pentenoic acid or pentenoate esters may result in the production of adipic acid esters such as monoesters (adipic acid monomethyl ester) or diesters (adipic acid dimethyl ester), which may be used as an important intermediate in the production of adipic acid (1,6-hexanedioic acid), which itself is an important precursor for inter alia the production of polyamides such as polyamide-6,6 or polyamide-4,6. Further, esters of adipic acid may be used in plasticisers, lubricants, solvent and in a variety of polyurethane resins. Other uses of adipic acid are as food acidulants, applications in adhesives, insecticides, tanning and dyeing.

  • step (a) of the process of the invention the actual carbonylation reaction takes place.
  • the process of the invention is carried out in the initial presence of alkene carbonylation product.
  • the inventors have surprisingly found out that the initial presence of alkene carbonylation product in the process of the invention may result in stabilisation of said catalyst system. This is all the more surprising since the reaction involves the production of alkene carbonylation product. Nevertheless, it appears that the alkene carbonylation product which is formed in the course of the reaction in step (a) by itself may not stabilise the catalyst system to the same extent as does the initial presence of alkene carbonylation product. At the start of a carbonylation process no or hardly any alkene carbonylation product is present.
  • the alkene carbonylation product in order to carry out the process of the invention, whether it is a repetitive batch or a continuous process, or any other type of process, the alkene carbonylation product must be added to the reaction medium in step (a) at least once. It would not be obvious to add the reaction product to a chemical conversion reaction, particularly on industrial scale. On the contrary, the reaction product is normally removed from the reaction as efficiently as possible in order to try to sell as much product as possible. Using the process of the invention may result in less formation of Pd black and/or in less inactivation of the catalyst system as compared to a repetitive or continuous carbonylation process which is carried out in the absence of initial carbonylation product. Formation of Pd black is an indication of inactivation of the catalyst.
  • the process of the invention is particularly advantageous in that no additional stabilizer needs to be added because the stabilizer is the alkene carbonylation product itself.
  • the alkene carbonylation product which is initially present in the process is not necessarily the alkene carbonylation product which is formed in the process of the invention.
  • the alkene carbonylation product which is initially present in the process may be the same as the alkene carbonylation product which is formed in the process of the invention.
  • the process of the invention involves methoxycarbonylation of methylpentenoate using methanol and CO resulting in the production of adipic acid methylester, such a process may be carried in the initial presence of adipic acid methylester.
  • the alkene carbonylation product which is initially present in the process may be a different alkene carbonylation product as compared to the alkene carbonylation product which is formed in the process of the invention.
  • the process of the invention involves methoxycarbonylation of ethene using methanol and CO resulting in the production of methylproprionate, such a process may be carried in the initial presence of adipic acid methylester.
  • the process of the invention involves methoxycarbonylation of methylpentenoate using methanol and CO resulting in the production of adipic acid methylester, such a process may be carried in the initial presence of methylproprionate.
  • the alkene carbonylation product which is initially present in the process may comprise at least part of the alkene carbonylation product which is formed in the process of the invention.
  • Using an initial alkene carbonylation product which comprises, or which is the same as the alkene carbonylation product which is formed in the process of the invention may be advantageous in that no additional stabilizer may have to be added.
  • Using an initial alkene carbonylation product which is different from the alkene carbonylation product which is formed in the process of the invention may be advantageous in that such initial alkene carbonylation product may not inhibit the reaction, or to a lesser extent.
  • alkene carbonylation product is added to the process only once, for example during the start-up of the process, when no alkene carbonylation product has yet been formed. As the process proceeds alkene carbonylation product is formed which may stabilize the catalyst system.
  • the initial alkene carbonylation product in the process may comprise at least 10% w/w of the alkene carbonylation product which is formed in the process of the invention, more preferably at least 20% w/w, at least 30% w/w, more preferably at least 40% w/w, at least 50% w/w, even more preferably at least 60% w/w, at least 70% w/w, even more preferably at least 80% w/w, at least 90% w/w.
